RUDOLPH NEUMANN, OF INDIANAPOLIS, INDIANA.

BUTT AND LOCK GAGE.

Liaaoaa.

To all whom it may concern Be it known that I, RUDOLPH NEUMANN, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Butt and Look Gages; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention comprehends improvements in door gages and relates more particularly to a gage which will be found useful in fixing hinges and locks to doors.

One of the objects of the invention is to provide a gage of this type which shall be of extremely simple construction, cheap to manufacture, strong, durable and very practical.

Another object of the invention is to provide a door gage including a body formed with a plurality of slots and channels to re ceive slidable and rotatable rods carrying marking elements, said rods being locked in their adjusted position by means of screws. The invention also aims to generally improve devices of this nature to render them more useful, practical and commercially desirable.

With these and other objects in view, as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a front side elevation of my improved gage, Fig. 2 is a rear end elevation thereof, Fig. 8 is a rear side elevation, Fig. 4: is a front end elevation, Fig. 5 is a top plan view, Fig. 6 is a bottom plan view, Fig. 7 is a vertical longitudinal section taken on the plane of line 77 of Fig. 2, Fig. 8 is a horizontal longitudinal section on the plane of line 88 of Fig. 2, Fig. 9 is a transverse section taken on the plane of line 99 of Fig. 1, Fig. 10 is a detail sectional view showing a portion of one of the threaded rods and the marking elements carried thereby, and Fig. 11 is a section on the plane of line 1l11 of Fig. 10.

Referring in detail to the drawing by Specification of Letters Patent.

numerals, 1 designates generally, the body of my improved gage, said body being in the general form of a rectangular block and being formed upon opposite sides with the recesses 2 and 8. These recesses cause the body to appear I-shaped in cross section, as clearly shown in Fig. 9. Transverse projections 4 and 5 are formed respectively upon the top and bottom of the block adj acent its front end 6 and have their rear faces 7 disposed in a plane at right angles to the planes of the upper and lower faces of the body. The central portion 8 of the body is formed above and below its horizontal center plane with the longitudinal bores, or channels 9 and 10, said channels being circular in cross section and opening upon the front end of the body. As shown in Fig. 7, the channels terminate short of the rear end 11 of the body and communicate with the exterior face thereof by means of circular openings 12.

Rotatable rods 13 and 14 extend through the openings 12 into the channels 9 and 10, said rods being knurled adjacent their rear ends, indicated by the numeral 15 and being also provided with oppositely threaded portions 16 and 17. A collar 18 is loosely mounted upon each of the rods between the threaded portions thereof, and are held against longitudinal movement relative to the rods by means of marking pins 19. These pins extend through transverse openings in the collar into annular grooves 20 formed in the rods, as clearly shown in Fig. 10. It will be noted that the portions of the rods around which the collars 18 fit, are unthreaded. It will also be noted, upon reference to Fig. 10, that the forward ends of the rods are of a somewhat smaller diameter than the unthreaded portions. The body 1 is provided upon its upper and lower faces with the longitudinal slots 21 and 22 which communicate with the channels 9 and 10 and which receive the marking pins 19 as well as the marking pins 23 carried by the collars 24 and 25. These last mentioned collars are internally threaded for engagement with the threaded portions of the rods 13 and 14. A set screw 26 threads into each of the collars 18 at right angles to the pins 19 carried thereby and works through the slots 27 formed in the front side of the central portion 8 of the body. "When these screws are set, the collars 18 are held against movement and the rods 13 and 14 may be rotated so as 'which communicates With-the end of theto move the pins 23 toward or away from each other.

' The central portion Softhe body is also formed with the longitudinal bores, or channels 28 and 29 which are circular in cross section, as clearly shown in Fig. 9, and Which receive the slide rods 30 and 31 respectively. 7 Each rod carries upon its rear end a plate 32 which is sharpened at one end,

as indicated by the numeral 33, to providea line marker. The slide rods are'h'eld againstlongitudinal movement by means of set screws 34 which thread into the same whichwork'through longitudinal slots 35, ascl'early shown in Figsl and 3; The slide rod 30 hasits locking screw positioned closer to its outer end than has the-slide rod 31and thereforethe last mentioned rod may be moved a greater distance rearwardly than the first mentioned rod.

The body is formed adjacent its front end with a transverse bore, or channel35,

block by means o'f the slot 36, said slot havingits side wall beveled in opposite directions adjacenttheir outer edges, as clearlyshown in Figs; 4 and 7.- A'- slide rod 37 works within the channel 35 and 'may' be held against longitudinal movement by ascrew' 38, the head of said screw being adapted to engage the beveled places 'ofthe wallsofthe slot 36. The rod 37 is provided with-a marking pin 39 and a marking plate 40, said'platebeing shaped to form a cutting edge 41. p

' When it is desired to mark the edge of a door to indicate'the position of-the lock receiving mortise, the locking screw-26 which holds the threaded rod 14 against longitudinal movement, is first loosened; Then the rod is shifted longitudinally so as to space When marking a door jamb, or frame, to

receive the keeper for the lock, the threaded Copies 'oi'i thi patent may' be'obtained for The locking pin 26 is then rod 13 is preferably employed and the slot 21 is graduated on each side thereof so that the center pin 19 may be set at a known distance from either end of the block. Sometimes the door frame, or jamb, is so formed as to make it impossible to use the flanges 4 and 5 as guides and then the center pin 19 is spaced a distance from the rear end of the block equal to half the width of the door face. In laying out the position of the mortises to receive the hinges, the sliding rods 29, 30 and 37 may be employed.

From the foregoing description taken in connection with the accompanying drawings, it will be seen that I have provided a very compact and practical door gage, which is'of" extremely simple construction, cheap to manufacture and easy to operate.

\Vhile I have shown and described the preferred embodiment of my invention, it willbe understood that minor changes in construction, combination and arrangement of parts may be made without departing from the scope and spirit of the invention as claimed.

Having thus described my invention, I cl'aim In a'gage of the character described, a body having a channel formed therein and provided with a slot opening upon one face and communicating with the channel, a rod extending into the channel provided with oppositely threaded portions and an unthreaded portion intermediate said threaded portions, the unthreaded portion being formed with a circumferential groove, a collar loosely mounted upon the unthreaded portion, a marking pin carried by the collar and extending into the circumferential groove, said pin projecting through said slot, a collar positioned upon each side of said first mentioned collar and threadingly engaging the rod, a marking pin carried by each of said second mentioned collars and projecting through said slots and a knurled extension formed integral with the rod to form'a thumb piece whereby the rod may be rotated,

In testimony whereof I afiix my signature in presence of two witnesses.

RUDOLPH NEUMANN.
